WebDec 30, 2016 · Explanation: To be “neutral” and atom must have the same number of protons as electrons. Usually it is the electrons that are shared, acquired or lost in chemical bonding. The “ground state” of an atom will have a fixed number of electrons that define its chemical properties. The number of electrons can be determined from an atom’s ... WebFrom the Table of Elements, we can see that mercury's atomic number is 80 and its atomic mass is 200.59. We'll need these numbers to get the information you want. The atomic number is the number of protons in an atom's nucleus, so we can tell right away that an atom of mercury contains 80 protons. Atoms, by definition, are electrically neutral.
